hw.device-type: Various fixes

[acostach]

• The Jetson TX2 NX has an eMMC and no SD-CARD slot
• The JN30B Nano uses the eMMC module and not the SD-CARD one
• The Radxa CM3 on RPI CM4 IOBoard as well as the Radxa zero use rockchip software tools in order to put the eMMC in mass-storage mode
• The CM4 module comes in two flavors: one with eMMC and the Lite version which uses the carrier board sd-card slot to load the image. Both use the same balenaOS image. I switched the storage to internal for this DT because it may have one, but this solely depends on the actual module. Another consideration is that this DT can also boot from a USB stick or a NVME drive connected to the mPCIE port.
